Percentage inhibition activity of Skeletonema costatum and Chaetoceros pseudocurvisetus by using the acetone/chloroform extraction method. Figure 3 reports the percentage inhibition activity of organic (O) and water (W) extracts of Skeletonema costatum FE85 and Chaetoceros pseudocurvisetus FE331 cultured in control and phosphate-starvation conditions (/1 and /3, respectively). Samples were extracted by using the acetone/chloroform method and tested at 800, 200 and 128 μg/mL.
